Mti Industries

<h3>About MTI Industries &amp; the Safe-T-Alert Brand</h3><p>MTI Industries is the manufacturer behind the trusted <strong>Safe-T-Alert</strong> line of safety alarms — a name that has become synonymous with reliable protection for RV owners, boaters, and outdoor adventurers. Focused exclusively on life-safety detection equipment, MTI designs and engineers alarms that guard against the invisible threats most likely to cause serious harm in confined spaces: carbon monoxide, propane and LP gas leaks, smoke, and combustible fumes.</p><p>What sets MTI Industries apart is a singular commitment to the environments where their products are actually used. Unlike household detectors built for stable, climate-controlled interiors, <a href="/7469-mti-industries-air-and-gas-leak-detector-201223">Safe-T-Alert gas leak detectors</a> are engineered to endure the vibration, shock, humidity, and extreme temperature swings that come with life on the road or water. Every alarm in the lineup is built to alert quickly and accurately without generating the nuisance false alarms that can cause users to disable critical safety equipment.</p><h3>Protecting RVs and Boats from Hidden Dangers</h3><p>Recreational vehicles and boats share a common challenge: they rely heavily on propane and other combustible fuels in tight, enclosed quarters — exactly the conditions where a slow leak or incomplete combustion can become life-threatening within minutes. MTI&apos;s <a href="/7469-mti-industries-carbon-monoxide-smoke-fume-detectors-200239">carbon monoxide, smoke, and fume detectors</a> are engineered with this reality in mind, offering standalone CO alarms, standalone smoke detectors, and popular dual-sensor units that monitor for both propane gas and carbon monoxide simultaneously in a single compact device.</p><p>For boaters, the hazards extend beyond gas — engine fumes and bilge vapors present their own risks. MTI&apos;s marine-grade detectors address these environments with sensors calibrated to avoid false triggers from common onboard smells like new boat off-gassing, while still catching real danger fast.</p><h3>Standards, Certifications &amp; Ease of Use</h3><p>MTI Industries products are designed to meet the rigorous standards set by organizations like UL, RVIA, and NFPA — certifications that matter when it comes to insurance compliance and campground regulations. Most Safe-T-Alert alarms run on 12V DC power, eliminating the need for frequent battery changes and making them a natural fit for RV and marine electrical systems. Installation is straightforward, and the product range covers both surface-mount and flush-mount configurations to suit a variety of vehicle layouts.</p><p>Beyond RVs and boats, Safe-T-Alert alarms also serve as dependable warning alarm solutions in workshops, cabins, and any space where gas appliances or engines operate nearby. Whether you&apos;re a weekend camper, a full-time RVer, or a seasoned boater, MTI Industries offers purpose-built safety solutions designed to travel with you.</p>

Product Details

The MTI Industries 45742WT is a flush-mount dual alarm system designed to detect both propane (LP) gas and carbon monoxide (CO) in recreational vehicles. This 12-volt alarm upgrades single-function propane detectors to a comprehensive dual-sensor system, replacing Safe-T-Alert Model 40-442 propane alarms and other outdated units over 5 years old.

Key Features:

  • Dual detection technology monitors both propane gas and carbon monoxide levels simultaneously
  • Flush-mount design with black finish for clean, integrated installation
  • 12-volt DC power operation eliminates the need for battery replacement
  • Alarm mute button allows temporary silencing while ventilating the RV
  • Rapid recovery sensor automatically resets after silencing or reactivates if dangerous levels persist
  • Meets RVIA/NFPA safety requirements and conforms to UL 1484 standards for RV applications

Ideal for Class A motorhomes, Class B van campers, Class C mini-motorhomes, travel trailers, fifth wheels, truck campers, and folding campers. This alarm provides essential dual-threat protection with reliable 12-volt operation and professional-grade safety compliance for peace of mind on the road.

great easy to use and simple for a old man who cant use computer very well thank you

Had a little trouble finding the item needed. A search option would be helpful.

I recently ordered an Invidia N1 exhaust system from autoplicity and to be honest I was concerned at first my order was not shipped for 2 days, I know I was just very impatient. I'm not sure how their business works but 2 days of processing? I emailed their shipping department and got an email back explaining everything and it also said I would get an email today or the next day and sure enough I did! Had the lowest price for the part I was looking for. Also all the good reviews just made me want to order from this company plus the good prices you can't go wrong.

Quick&amp;easy

easy to navigate site and had the parts I needed at a reasonable cost.
